Sun, 2 Mar 2008 15:24:42 +0100
Hi,
i've got a 32bit bitmap including alpha channel. I pass this to a certain
application. There's a hook for gdi32.BitBlt where i wait for this image to
be drawn by the application and instead i call AlphaBlend (i do

I wish to draw a circular/angle gradient with GDI+. Unlike a radial
gradient where the color change is a function of the distance from the
